Gravity measurements on summer sea ice in the Beaufort and Chukchi seas, 1976
Gary Boucher
1977, Open-File Report 77-705
During September, 1976, a series of gravity measurements was made in the western Beaufort Sea and the northern Chukchi Sea on ice floes and on a grounded ice island. The data were taken to evaluate the technique of measuring gravity on small ice floes in summer and to supplement and...
Binorm-a fortran subroutine to calculate the percentiles of a standardized binormal distribution
R.B. McCammon
1977, Computers & Geosciences (3) 335-339
BINORM is a FORTRAN subroutine for calculating the percentiles of a standardized binormal distribution. By using a linear transformation, the percentiles of a binormal distribution can be obtained. The percentiles of a binormal distribution are useful for plotting purposes, for establishing confidence intervals, and for sampling from a mixed population...

Breeding avifauna of the south San Francisco Bay estuary
Robert E. Gill Jr.
1977, Western Birds (8) 1-12
San Francisco Bay represents one of the largest estuarine areas on the Pacific Coast of North America. Its open waters, tidal flats, tidal marshes and solar evaporation ponds provide critical foraging, resting and breeding habitat for migratory and resident birds. The avifauna of San Francisco Bay has received considerable attention;...
Anisotropic magnetic susceptibility of erbium and ytterbium in zircon, ZrSiO4
A. N. Thorpe, Charles Briggs, T. Tsang, F. Senftle, Corrine Alexander
1977, Journal of Physics and Chemistry of Solids (38) 477-480
Magnetic susceptibility measurements have been made for both Er- and Yb-doped (1̃03ppm) zircon single crystals with the magnetic field perpendicular and parallel to the [001] axis. Large susceptibility anisotropies were found in both cases. Our observed anisotropies of ZrSiO4: Yb indicate small populations (1̃9%) of Yb ions at the axial...

Ore transport and deposition in the Red Sea geothermal system: a geochemical model
Wayne C. Shanks III, J. L. Bischoff
1977, Geochimica et Cosmochimica Acta (41) 1507-1519
Thermodynamic calculation of distribution of dissolved aqueous species in the Red Sea geothermal brine provides a model of ore transport and deposition in good agreement with observed accumulations of base metal sulfides, anhydrite, and barite.The Red Sea brine is recirculated seawater that acquires high salinity by low-temperature interaction with Miocene...

M. Fishman, Roberto Spencer
1977, Analytical Chemistry (49) 1599-1602
An automated method to determine both inorganic and organic forms of arsenic In water, water-suspended mixtures, and streambed materials Is described. Organic arsenic-containing compounds are decomposed by either ultraviolet radiation or by suHurlc acid-potassium persulfate digestion. The arsenic liberated, with Inorganic arsenic originally present, is reduced to arsine with sodium...
Revised age for Midway volcano, Hawaiian volcanic chain
G. B. Dalrymple, D.A. Clague, M. A. Lanphere
1977, Earth and Planetary Science Letters (37) 107-116
New conventional K-Ar,40Ar/39Ar, and petrochemical data on alkalic basalt pebbles from the basalt conglomerate overlying tholeiitic flows in the Midway drill hole show that Midway evolved past the tholeiitic shield-building stage and erupted lavas of the alkalic suite27.0 ± 0.6m.y. ago. The data also show that previously published conventional K-Ar ages...

Further paleomagnetic results for the San Juan volcanic field of southern Colorado
M. E. Beck Jr., S.D. Sheriff, J. F. Diehl, E.A. Hailwood, P. W. Lipman
1977, Earth and Planetary Science Letters (37) 124-130
Combining paleomagnetic data for 17 new sites from the northwest portion of the (Oligocene) San Juan volcanic field of southern Colorado with data for 29 sites previously published yields a paleomagnetic pole at 85°N, 114°E (with a 95% confidence circle of...
Moon-Mercury: Relative preservation states of secondary craters
D. H. Scott
1977, Physics of the Earth and Planetary Interiors (15) 173-178
Geologic mapping of the Kuiper quadrangle of Mercury and other geologic studies of the planet indicate that secondary craters are much better preserved than those on the moon around primary craters of similar size and morphology. Among the oldest recognized secondary craters on the moon associated with craters 100 km...

A total of 161 blood samples collected from 77 white-tailed does (Odocoileus virginianus borealis) during the years 1971 through 1974 in Minnesota were utilized to make a preliminary characterization of the estrogen and progesterone levels in pregnant and nonpregnant animals. Progesterone and estrogen were measured by radioimmunoassay. Progesterone levels during...
The chronic toxicity of 3-chloro-4-methyl benzamine HCl to birds

3-Chloro-4-methyl benzamine HCl (DRC-1339), an avian toxicant, was fed to five species of birds for periods up to 120 days. The 30-day LC50 of uniformly treated feed for starlings was 4.7 ppm and the 90-day LC50 was 1.0 ppm. The 28-day LC50 for coturnix was 18 ppm. The 30-day LC50 for pigeons was...
Implications of a magnetic model of the Long Valley caldera, California
D.L. Williams, F. Berkman, Edward A. Mankinen
1977, Journal of Geophysical Research (82) 3030-3038
A quantitative magnetic model of Long Valley, California, shows that the magnetic field above this caldera is dominated by intracaldera Bishop tuff, part of the ash flow tuff whose eruption precipitated the caldera collapse. We propose that about half of the 350 km3 of intracaldera Bishop tuff, or that part beneath...

Experimental groups of coho salmon (Oncorhynchus kisutch) of transferring types AA and AC were compared to determine relative growth and survival before release, yields from the fishery, and returns of fish to the hatchery as 2- and 3-yr-olds. In the hatchery, growth was faster and survival higher in the AA...

Earthquakes and plate tectonics
H. Spall
1977, Earthquake Information Bulletin (USGS) (9) 14-17
The world's earthquakes are not randomly distributed over the Earth's surface. They tend to be concentrated in narrow zones. Why is this? And why are volcanoes and mountain ranges also found in these zones too? An explanation is to be found in plate tectonics, a concept which has revolutionized thinking in...

Landslides
T. H. Nilsen
1977, Earthquake Information Bulletin (USGS) (9) 27-33
Landslides are frequent in areas where there is high seismicity and steep slopes. Landslides associated with earthquakes may cause as much damage as the initial ground shaking. They may also occur long after the earthquake. Some of the major earthquakes that have occurred during the past 15 years demonstrate the hazards...
